About the Bombardier Learjet 31
Bombardier Learjet 31A
The Learjet 31 (and its upgraded variant, the 31A) is the definitive “hot rod” of the light corporate jet world. By mating the fuselage of the Learjet 35/36 with the large “Longhorn” wing of the Learjet 55, Bombardier created an aircraft with exceptional climb performance and runway capabilities. It is widely regarded as a pilot’s airplane, prioritizing raw performance and handling over cabin volume.
Key Features for GA Buyers
- Unmatched Climb Performance: With a climb rate exceeding 5,000 fpm, the Learjet 31 can reach its service ceiling of 51,000 ft faster than almost any other civil aircraft. This allows owners to top almost all weather and commercial traffic.
- Runway Agility: The large wing area provides excellent low-speed handling, allowing the jet to operate out of shorter runways (approx. 3,500 ft) than many competitors in its class.
- Speed: It is one of the fastest light jets available, with a high-speed cruise of 456 knots (Mach 0.81).
Trade-offs
- Range Limitations: Unlike the Learjet 35, the 31 lacks tip tanks to preserve the aerodynamic benefits of the Longhorn wing. This restricts range to roughly 1,250 nm, making it a short-to-mid-range sprinter rather than a cross-country endurance runner.
- Cabin Size: The cabin is based on the original Learjet cross-section, which is relatively tight (4 ft 11 in wide, 4 ft 4 in high). It typically seats 6-8 passengers, but headroom is limited.
- Baggage: External baggage storage is limited compared to newer designs, which can be a constraint for fully loaded trips.
